I’ve written on this subject before, but we had a recent incident in which the radio system did not work when they went to back it up. When we build these radio systems, unless not budgeted for, we put in some type of backup system to allow for the continued radio operation in case of a failure. Granted, the backup system may be as simple as a mobile radio with a power supply, but it is something to communicate to the end users that there is a problem with the system. Not only is the backup radio essential but some type of plan or Standard Operating Procedure should be written and followed. During a crisis or emergency, the last thing you need to be thinking about is “What do I do now!”. Instead, having a documented plan in a place is key to a good emergency plan.
